Non Idle idle?

[kcoelhoe30]

Ive been working on my project car and finally got it back togather today but when i started the car i realised a difference in the idle, it is now at 1500rpms idle and its not exactly "idle" its reving up and down constantly and idk what it is...
Any help?

All connections tight and in the right spot? I experienced a crazy idle after I forgot to connect my maf sensor after motor work. Probably something stupid you forgot. I doubt it would idle that high if its a vac leak and it the leak was that big the car wouldn't stay running

My was at 1100 and would jump to 2000 when I turned on the AC. I traced it to a bad throttle position switch. Also check out your idle control valve.
